2 mic hat kernal dtoverlay problems

I’m a complete noob and need a bit (lot) of guidance in this field. I have tried to use the ReSpeaker 2 mic hat on a pi zero 2 and a Pi5 with both failing miserably. I have got it down to the dtoverlay for the kernel header not starting. I have tried new up-to-date versions, I tried legacy versions with mis-matched kernel-header problems. Please help…someone!!!
